HS Code for HFC-134

HS code 2903.45 is used for the classification of specific saturated fluorinated derivatives of acyclic hydrocarbons, namely 1,1,1,2-tetrafluoroethane (commonly known as HFC-134a) and 1,1,2,2-tetrafluoroethane (HFC-134). These substances are classified under Chapter 29, which encompasses organic chemicals. Heading 2903 is dedicated to halogenated derivatives of hydrocarbons. The classification logic follows the chemical structure: these are acyclic (open-chain) hydrocarbons where hydrogen atoms have been replaced by fluorine atoms. Because they are \"saturated,\" they contain only single bonds between carbon atoms. HFC-134a is one of the most widely used refrigerants in mobile air conditioning and domestic refrigeration. The HS system provides specific subheadings for these fluorinated hydrocarbons to facilitate the monitoring of greenhouse gases under the Kigali Amendment to the Montreal Protocol. It is important to note that this code applies to the pure chemical compounds. If these gases are mixed with other refrigerants or oils, the classification may shift to Chapter 38, specifically heading 3824 or 3827 depending on the mixture composition.

Products Included

• Pure 1,1,1,2-Tetrafluoroethane (HFC-134a)
• Pure 1,1,2,2-Tetrafluoroethane (HFC-134)
• Refrigerant gas HFC-134a in cylinders
• HFC-134a used as an aerosol propellant
• Saturated fluorinated acyclic hydrocarbons (specific to 134 series)

Common Misclassification

A common misclassification is HS code 3824.78 (or 3827.31 in newer versions), which covers refrigerant mixtures containing HFCs. If HFC-134a is blended with other gases like HFC-125, it cannot stay in 2903.45. Another error is 2903.41, which covers different fluorinated derivatives like trifluoromethane. Importers must ensure the chemical purity exceeds 95% to remain in Chapter 29.

FAQ

What is the HS code for HFC-134a?

The HS code for pure HFC-134a (1,1,1,2-tetrafluoroethane) is 2903.45.

Is HFC-134a classified differently if it contains lubricant?

Yes, if HFC-134a is imported pre-mixed with compressor oil, it is generally classified as a preparation under Chapter 38 rather than a pure chemical in Chapter 29.
